Further, the signal processor is equipped with the clamping device for fixing the test bar, the clamping dress
Setting can move up and down；
Storage unit, analytical unit and output unit are equipped in the signal processor.
Further, the signal processor further includes telescopic rod, and one end of the telescopic rod is connected with the test bar,
The other end is connect with the clamping device.
Further, the detector is equipped with pressure sensor, the pressure sensor with the end of touching of threaded hole to be measured
With the signal processing mechatronics.
Further, the detector is cylindrical detector.
Further, the detection handle is equipped with level meter.
By above-mentioned technical proposal, the threaded hole center of circle detection device of the utility model is had at least the following advantages:
The utility model is by will test the detector of stick and the thread crest inscribe of workpiece for measurement, accurately to measure up and down

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
As shown, the threaded hole center of circle detection device of the present embodiment includes test bar and the letter that connect with the test bar
Number processor, detector 4 of the test bar by detection handle 1 and set on detection 1 one end of handle form, and detector 4 is from screw thread to be measured
3 one end of hole is protruded into, and the crest inscribe up and down with threaded hole 3 to be measured, the inscribe refers to 2 shape of detector and threaded hole to be measured
The positional relationship for the circle that 3 crests are formed in axial projection.
The other end of test bar is connected with signal processor, and signal processor is equipped with to be filled for the clamping of fixed test stick
It sets, clamping device can move up and down；It is equipped with storage unit, analytical unit and output unit in signal processor, uses respectively
In the range information for storing about the 3 crest range calibration face of threaded hole to be measured that the test bar transmits, to the range information point
Analysis processing calculates the center location and output test result of threaded hole 3 to be measured；Detector 4 is set with the end of touching of threaded hole 3 to be measured
